Portland woke up on the chilly side Sunday, April 26, with temperatures hovering around 43°F at PDX, but the city is headed for a spring afternoon in the upper 60s to around 70°F. Light north-northwest winds will keep things feeling comfortable across the metro, so it is a solid day for errands, patio time, or a quick walk along the river. Most of the stretch through midweek looks dry, with only a brief shot at light showers near the mountains early next week.
Afternoon Warm-Up
Temperatures will climb steadily through the morning, landing in the mid to upper 60s by early afternoon and peaking near 70°F later in the day. Skies should stay mostly sunny, with only a slight chance of any stray sprinkles. North-northwest winds around 1-6 mph will keep outdoor plans comfortable. Inland neighborhoods can expect to run a few degrees warmer than spots right along the river.
Frost Advisory East Of The Metro
Before sunrise, a Frost Advisory was posted for parts of the Upper Hood River Valley (ORZ121), set to last until 8 AM PDT. It mainly targets low-lying rural areas and does not include Portland itself. If you have sensitive plants in those colder pockets, the National Weather Service Portland recommends bringing potted plants inside or covering them.
Coast, Mountains, And Week Ahead
On the coast, look for morning low clouds and some patchy fog before gradual clearing. Up in the Cascades, there is a chance for a few light showers Monday and Tuesday, while valley rain chances stay low. A ridge builds in by midweek and should nudge highs into the low to mid 70s on Wednesday and Thursday, with some inland areas flirting with the upper 70s by Thursday. For more on the setup and this month’s recent frosty starts, there is some useful context from earlier in the week.
What To Pack
Plan on a light jacket or sweater for the cool morning, then dress for mild, sunny afternoons. Sunglasses and a reusable water bottle should cover most daytime plans. Gardeners in valley cold spots will want to keep protecting tender plants through Monday morning. Out on the water, mariners should stay mindful of 5 to 7 foot seas along the coast this week.
